https://discord.gg/rdwrXW2b is my discord, I have a Adult asset section. Or you can DM me, name is just Wuffwick

Have you installed VRCFury? That could be the issue or if you do not have the latest VRC SDK. Otherwise is there anything unique about the avatar that could mean VRCFury is not able to find the avatar hands. My DMs are open on discord if you needed more help to troubleshoot what the issue could be.

To change colors you will need to use the poiyomi shader version applied to the mesh

You can buy it right here, but I would suggest looking up how to upload avatars for VRChat first. There are several videos outlining the concept and process as it is not a simple thing. 

The max Bytes you can have on an avatar synced is 256. Depending on all that you have on the avatar you will need to remove/tweak what is there. the dildo uses 21 synced parameters by default but you can open "CanineDildo_Parameters Merge" and unchecked 'Synced' for "DildoHue" if you are not using poyomi or dont care about being able to change the colors in game.  Depending on the setup of the base avatar it may have face tracking which you could also remove/tweak if you are not needing it as Face tracking takes up massive amounts of synced parameters.

There is a quest compatible prefab in the project. Its in the CanineDildo/Prefabs/Quest folder. Is that what you meant

yes that is possible, Though you would not have the floppy motion from physbones on each unless you added it yourself. But yes you could add in new models and keep the other functions

Make sure your VRC SDK is updated for the latest constraints. I found the issue with the vibrate and color wheel and the latest 1.11 file will fix that! For the color wheel you will need to use the poiyomi shader

Today is that day! The 1.1 package is now updated with a quest version using the new constraint system!

Not yet, the current version of VRC does not have Constraints for quest but the next update in Beta will! After that is released all my assets will be synced for quest and PC.
